All, I am trying to implement fax detection on FreeSwitch within a dialplan that routes inbound calls from a BRI (Sangoma), to an Asterisk (Trixbox) machine handling the extensions. I am only doing this until I can get British English sounds for FS ;-). The inbound route without any fax detection works fine, ie the caller hears ringing until the Trixbox extension is either answered or hits voicemail: <extension name="60xto35x" > <condition field="source" expression="freetdm"/> <condition field="context" expression="public"/> <condition field="destination_number" expression="60([0-5])"> <action application="bridge" data="sofia/external/35$1@192.168.24.15"/> </condition> </extension> The closest I have got to adding the fax detection is the following: <extension name="60xto35x_copy" > <condition field="source" expression="freetdm"/> <condition field="context" expression="public"/> <condition field="destination_number" expression="60([0-5])"> <action application="tone_detect" data="fax 1100 r +5000 transfer '620 XML default'"/> <action application="answer"/> <action application="playback" data="tone_stream://$${uk-ring};loops=3"/> <action application="bridge" data="sofia/external/35$1@192.168.24.15"/> </condition> </extension> I had to add the playback so the caller would hear ringing during the tone_detect timeout. However, as soon as the tone_stream finishes, and the call is bridged to the Trixbox, the caller hears silence instead of ringing. Is there any way to pass the ringing from the extension back to the caller coming in on the BRI circuit, or otherwise fake it until the remote extension is answered?
